PROJECT ASSURE

ASSUREDLY
Sherlock Holmes!

The Best Synthetic Diamond Detector is ASSUREDLY Sherlock Holmes.

The ASSURE program is an initiative of the Diamond Producers Association (DPA).
The impartiality of the data was checked by UL Laboratories.

Did you know the ASSURE Program is ongoing? That’s how important it is to be able to detect synthetic diamonds.

If there is ever a better synthetic diamond detector than the Sherlock Holmes by Yehuda, the ASSURE Program will let you know.

The complete list of test results – in alphabetical order – can be found at the ASSURE directory: https://diamondproducers.com/assure/assure-directory/

31 detectors have been comprehensively tested by ASSURE.
ASSURE comprehensively analyzes all 3 types of synthetic diamond detectors.

Three Types of Synthetic Diamond Detectors:

TYPE ONE
Detectors that can check only one stone at a time (mounted or loose)

TYPE TWO
Detectors that sort small (under 0.20 ct.) round diamonds into 2 groups – natural and synthetic. (Primarily used by gem labs).

TYPE THREE
Detectors that can check single stones (mounted or loose) AND multiple loose stones AND multiple mounted jewelry.

You need type three, right?

  • The Sherlock Holmes by Yehuda is type three.
  • Sherlock can check single stones, loose or mounted.
  • Sherlock can check a parcel of stones.
  • Sherlock can check jewelry pieces that are mounted with numerous stones

Of the 31 detectors comprehensively tested by the ASSURE program, only 15 were type three. The ASSURE program checked 2 different groups of diamonds by size:

1. Small diamonds under 2mm diameter.
2. Any larger diamond.

SH 3.0 uses the same detection technology as the SH 2.0
